The AMG1051H ultra-thin circuit power supply isolation temperature transmitter digitally linearises the signals of the field thermocouple (TC) or resistance temperature detector (RTD), converting them to isolated outputs of 4-20mA current corresponding to the sensors' temperatures. Isolators have the functions to send out alert messages when the sensors sense a disconnection, and the RC input has an auto cold junction compensation function. It is also able to configure parameters such as scale and index number for the transmitter using professional software.

1) The surrounding environment should not have electromagnetic induction effects such as strong vibrations, shocks, major currents and sparks, and there should not be any substance in the air that would corrode the chromium, nickel, or silver plating, and there should not be flammable or explosive substances.

(2) Continuous working temperature: -20℃ - ＋60℃;

(3) Storage temperature: -40℃ - ＋80℃;

(4) Relative humidity: 10% -90%RH.

Applications:

Note: 1. while three-wire thermal resistance signal inputting, as far as possible to ensure the resistance value of three wires are equal;

2. While two-wire thermal resistance signal inputting, terminals 6 and 7 must be short circuited.

Note: 1. The output precision of "%" is equivalent to the range of the set, take larger value of range deviation and absolute deviation in the application.

2. The output precision does not include cold end compensating deviation whileTC inputting.
